1.Starting with this provided code, add the following functionality: Replace hardcoded strings “Zero”, “One”, “Two”, “Three” in the ArrayList based on user typed input (use Scanner or JOptionPane classes). The user will be prompted for the String to be stored in the ArrayList and then hit enter. The user will be able to continue to add items to the ArrayList until they just hit enter without typing anything. Once the user does this (hits enter without typing anything), the program will display all of the elements of the ArrayList, both the index and String values, in a table. It will do this via a single loop making use of an iterator method. 2. Starting with this provided code, add the following functionality: Use a Try/Catch block so that the exception is caught and the program exits a bit more gracefully. Save this file as TryCatch.java.

THE AMERICAN REVOLUTION AND THE EARLY REPUBLIC

By
Assignment Overview The American Revolution and Independence As we saw in the Module Overview, there were numerous factors that ultimately led to revolution and independence. In this second Case assignment, you’ll be researching and writing about some of those factors. Case Assignment Write a 3 to 4-page essay identifying at least FOUR factors which led to colonial independence. In your paper, explain which events triggered discord between the colonies and the Mother Country. Be sure to do some research on your own and use other resources to analyze the thought-processes which sparked independent thinking. The best way to approach and organize the paper would be to create a title for each event and then discuss your findings. For example; for the first one you could write, “Event 1, The Seven Years War”. This would be followed by your narrative on how this war led to independence. The rest of the paper would follow this pattern. Assignment Expectations Use concepts from the background
